I'm fairly sure its due to my creative tab class.

FINAL EDIT: I have solved the problem, everything works as intended, and is now working in the way I was originally hoping.

I'm fairly sure it's something to do with my creative tab, I'm trying to order it manually.

Added link to gist.

Gist updated, now I'm getting 'mouseReleased event handler', new development: the game will launch , but the game crashes as soon as I try to click into the creative tab.

Can you tell me what the recommended way of ordering a creative tab is?

Gist updated, What's the most common way of ordering a creative tab?

Line 25 points to this:

ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());

Are you sure the code matches up with the crash report? I can't imagine what would throw a NPE on that line.

 

Override fill, call super, sort the list.

I can't imagine what else could be throwing the error, and what I'm trying to do is overwrite the fill method.
